Detection of an undescended parathyroid adenoma with 18F-fluorocholine PET/CT

Abstract

Abstract Surgical excision of a parathyroid adenoma (PTA) is the only curative treatment for primary hyperparathyroidism (PHP). The transition from routine bilateral neck exploration to minimally invasive parathyroidectomy has been made possible by preoperative location techniques, including molecular imaging. Here, we present a case of a 76-year-old man with PHP who underwent a [18F]fluorocholine PET/CT scan, which showed a rare undescended PTA at the level of the right carotid bifurcation. After a successful minimally invasive parathyroidectomy, a PTA was confirmed, and the parathyroid hormone level normalized within 24 h. We conclude that it is relevant to locate preoperatively a PTA accurately to assist the surgeon to perform a successful minimally invasive parathyroidectomy.
